The correct option is Company managed Kanban project.

A Company managed Kanban project provides a dedicated backlog column and flexible board columns so the team can keep an extensive backlog in its own column while work flows through the board. It also supports robust board configuration and advanced reports such as the cumulative flow diagram and control chart so the team can produce visual reports that group and surface issues. Company managed projects offer configurable quick filters and card highlighting so high priority issues can be located quickly on the board.

Scrum team managed project is not ideal because Scrum focuses on timeboxed sprints and sprint planning rather than a continuous backlog column on the board, and team managed projects have fewer built in reporting and configuration options.

Kanban team managed project provides a simple Kanban board but it has more limited customization and fewer advanced reports than a company managed project, so it may not meet the requirement for visual reports that group issues at scale.

Company managed Scrum project is not the best fit because Scrum projects organize work into sprints and are not focused on a single continuous backlog column and flow, so locating and visualizing a large, continuously managed backlog is harder than with a Kanban setup.
